Why does it sting so much when I take humira (adalimumab)? It's not the needle, it's the drug itself when I am injecting it

Humira (adalimumab) hurts. Humira (adalimumab) is a great drug in terms of its effectiveness for arthritis, uveitis, inflammatory bowel disease and other autoimmune but it hurts everyone who gets this medication. I have spoken to Humira (adalimumab) drug reps about this since i prescribe it to kids. There is something in the formulation that causes the stinging. Try warming med to body temp under your arm for 10 min before injecting. It helps some.
